Cisco

Global leader in networking and IT infrastructure; peripheral participant in AdTech through acquisitions of media and analytics technology companies

Cisco Systems is one of the world's largest networking and IT infrastructure companies, headquartered in San Jose, California. Founded in 1984, Cisco designs, manufactures, and sells networking hardware, software, and telecommunications equipment. While not a core AdTech company, Cisco has intersected with the digital advertising and media technology ecosystem through strategic acquisitions, most notably its purchase of Videoscape and related video delivery technologies, as well as its acquisition of companies like Cognitive Systems and others with analytics and data capabilities relevant to media and advertising. Cisco's relevance to AdTech stems primarily from its infrastructure role in powering digital media delivery, video streaming, and data analytics platforms. Its Cisco Jasper IoT platform, video networking solutions, and data center technologies underpin much of the internet infrastructure that AdTech companies rely upon. Additionally, Cisco acquired companies such as Sourcefire, OpenDNS, and others that touch on data intelligence and audience insights at the network level. In the AdTech lineage context, Cisco is recorded as an acquirer or parent of one or more AdTech-adjacent companies, reflecting its history of acquiring technology firms that serve media, analytics, and digital delivery markets. While Cisco itself is not an AdTech vendor, its portfolio has included technologies that serve broadcasters, content distributors, and digital media operators who are active participants in the advertising ecosystem.
